I'm loving my D5200, but have recently read about the 18-105mm lens I have for it being a plastic mount and subsequently a lot of people seem to have broken theirs at one point or another. Now I'm scared to death to use it! So I began looking at some other options for lenses with a metal mount and it seems Canon makes you invest quite a bit of money for a medium zoom lens with metalMounts. The first lens up is the AF-S 24-85mm at $600, then the 16-85mm at $630, and an 18-200mm at $800, and finally the 17-55mm at $1300...I only wish there were more options for less money like Canon seems to have, but I suppose it is what it is.

I have 18-70 with is metal all my other lenses are plastic never got a problems.
